Rays of light pouring in from above, bubbles drifting upward, colorful coral and tropical fish. Underwater motifs on their own make an image magical and refreshing. It's a theme Rinka always wants to draw when summer comes. In this article I'll introduce tags for drawing the ocean and underwater scenes beautifully, plus tips for bringing out the clarity of blue.

Start with the basic underwater and ocean tags

An underwater scene starts by deciding the environment tags for the setting. Shallows, deep sea or coral reef completely changes the mood, so it's handy to know the basic words.

Sea creature and coral tags

To liven up an underwater scene, scattering fish and creatures is the best way. Make one or two kinds the stars and add small schools around them for a balanced result. Creatures also create a story.

How do you get light rays and bubbles for clarity?

The biggest factors that make it look underwater are light and bubbles. Just having rays of light streaming in from the surface (caustics) and rising bubbles makes it look like real water. This is where you can show your skill.

For light rays, sunlight rays and caustics work well, and for shifting light and shadow, underwater lighting is effective. For bubbles, build around bubbles and add air bubbles for fine bubbles; clarity and depth increase dramatically.

`sunlight rays`	light rays	Light shining in from the surface. Key to the dreamy feel
`caustics`	caustics (rippling water light)	Net-like light patterns cast on the seabed
`underwater lighting`	underwater lighting	Shifting light and shadow for a three-dimensional look
`bubbles`	bubbles	A great supporting element that instantly says underwater

Blue gradients and a dreamy color scheme

The beauty of underwater scenes is, above all, the blue gradient. Paying attention to shades of blue, from pale aqua to deep ultramarine, creates depth and clarity. Adding one accent color tightens up the image.

Finally, here are small tricks to elevate an underwater scene into something dreamlike. Light, drifting hair and a unified color scheme are the key points. Nail these and the quality goes way up.

Rinka's tips

Let hair and clothes drift with floating hair or flowing to create the buoyancy of water and make it instantly look underwater
Unify everything in blues and add just one accent color, like a clownfish's orange or coral pink, to balance calm and color

FAQ

Frequently Asked Questions

It's supposed to be underwater but looks like it's in the air.

First add underwater, then add bubbles with bubbles or air bubbles; that works best. Adding incoming light with sunlight rays or caustics brings out the weight and clarity of water and makes it look underwater right away. Letting the hair drift with floating hair is also effective.

I want a dreamy, fantasy-like underwater scene.

Combining jellyfish with glowing creates a mysterious world with glowing jellyfish drifting by. Keep it to dark blues with deep sea and underwater lighting and scatter air bubbles for a quiet, magical deep-sea scene. Adding ethereal or serene deepens the mood further.

Everything turns into one flat blue.

Think in blue gradients (blue gradient) and mix pale aqua with deep ultramarine for depth. Then add just one complementary color, like a clownfish's orange or pink coral, to tighten up the image. Creating bright areas with sunlight rays also adds contrast between light and dark.
